Powder insufflator



Feb. 14, 1939. P. GOLDENTHAL POWDER INSUFFLATOR Filed Sept. 28 1937 INVENTOR PHIL/P GOLDE/VTHAL I TTORNEY Patented Feb. 14, 1939 UNITED STATES PATENT OFFICE POWDER- msurrm'ron Philip Goldenthal, Brooklyn, N, ,Y. 7 Application September 28, 11937, Serial No. 166,073 7 Claims. (allied-1266i This invention relates to powder insufliators particularly adapted for discharging medicinal powder into certain cavities of the human body.

The invention seeks to provide a simplified and 5 improved device for holding and applying a charge of powder in position for proper insufllation into a cavity.

The invention further contemplates the provision of an insufllator having improved means for receiving and holding a powder charged tube or cartridge, said powder being adapted for injection into a body cavity as by means of insufiiation, aiforded through the medium of a bulb.

More specifically, the invention contemplates an insuiilator having a removable tip portion with which is carried a cartridge-supporting cradle for rendering simpler and easier the positioning of a powder cartridge in the insuiilator and the removal of an emptied cartridge after discharge of the powder therefrom.

The foregoing objects and features of the invention and others which will be later apparent, are realized in the preferred embodiments of the invention as illustrated in the accompanying drawing and which are described in detail in the following specification.

In the drawing: 7

Figure 1 is a side elevational view of an insuiliator of preferred construction, parts being shown in sectional detail.

Figure 2 is an enlarged longitudinal section view of the nozzle end of the insufflator in one formof its embodiment.

Figure 3 is an elevational side view of the com- 7 bined nozzle tip and cartridge-holding cradle.

Figure. 4 is a similar view, partly in section, of a combined nozzle tip and cartridge-holding cradle of modified construction.

Figure 5 is a cross-sectional view as taken along the line 5-5 of Figure 4.

Referring to the drawing in greater detail, the insufflator' comprises a bulb in and a nozzle ll connected as by means of 2. preferably bent tube It. a a In its preferred design the bulb is provided with an air inlet valve check egress of air from the bulb at the end to which this valve is applied. The end of the bulb connecting with the tube I2 is also provided with a check valve l4 past which air from the bulb may be forced through the tube l2 and thus 7 through the nozzle l I.

The foregoing structure is of quite conventional design and may be varied in many ways. As contemplated in the present invention, the

I3 which also acts to end of the nozzle II is internally threaded at IE to receive the threaded reduced portion [6 of a nozzle tip I! forming a continuation of the nozzle. The mentioned tip is provided with a longitudinal bore E8 of somewhat smaller diameter than 5 the passage in the nozzle. For convenience in applying and removing the tip, the surface thereof is provided with a roughened or knurled por tion l9.

In the form of the invention shown in Figs. 2 l0 and 3, the tip I1 is integrally formed with a substantially semi-circular cradle portion 20 having a ring-shaped end 2| at the end remote from the tip IT. The mentioned cradle is adapted to be disposed within the nozzle II and to loosely fit 5 therein.-

The cradle thus formed provides a cavity into which a cartridge 22 containing tightly packed powder, may be inserted. In this manner, the powder is positioned in the path of a puff or blast 20 of air directed through the nozzle from the bulb l l whereby said powder is blown through the bore l8 in the tip I1.

As shown in Figs. 4 and 5, the cradle maybe formed of a wire ring 23 soldered, brazed, or 25 welded to the tip, a wire ring 24 commensurate to the ring-shaped portion 2|, and several longitiudinally disposed wire members 25 arranged, as shown, to form a cradle for the support of a powder-filled cartridge 22. 30

From the foregoing, it is apparent that a charge of powder may be inserted in the insufilator in a quick and easy manner as follows:

The tip I1 is unscrewed from the nozzle to expose the cradle cavity, a cartridge, with its ends 35 removed, is placed into said cavity, and the tip replaced. The insuffiator is now ready for use. Removal of the empty cartridge tube is as readily accomplished.

It will be noted that the insufllator parts are 40 arranged for easy cleaning and sterilizing and for this purpose the nozzle II and tube l2 may be unscrewed as at 26 from the bulb [0.

While the invention is quite simple in its construction, it is apparent that skilled persons may 45 vary the design and arrangement within the spirit and scope of the invention as claimed. For this reason, the prior art rather than the instant disclosure should form the basis of interpretation of the scope of the invention. 50

What is claimed as new and desired to be obtained by Letters Patent, is: V

1. In an insuiflator, a hollow nozzle, a tip for said nozzle having threaded engagement therewith, and a separate cartridge receiving portion 55 the hollow of said nozzle.

2. In an insufliator, a nozzle tip having a 10ngitudinal bore, and a cradle forming part of said tip for receiving a powder-filled cartridge for coaxial arrangement with said bore, said cradle comprising a semicylindrical portion having a ring-shaped end adapted to engage one end of said cartridge. 7

3. In an insufilator anozzleltip forattachment to a nozzle and havingv aIlongitudinahbore,:anda cradle forming part of said tip for receiving a powder-filled cartridge for coaxial arrangementv with said bore, said cradle comprising a plurality of longitudinally disposed members terminating in a ring-shaped end adapted to engage oneend of said cartridge, and wholly insertable in said nozzle.

4. In an insufiiator, a nozzle comprising a barrel 2,147,158 formed with said tip and wholly disposed within having an open end, and a nozzle tip having a longitudinal bore, a cradle forming part of said tip for receiving a powder-filled cartridge for coaxial arrangement with said bore, said cradle being wholly receivable in said barrel and said barrel and tip being threadably engageable to retain the cradle and cartridge within said barrel.

5. A powder insufliator comprising a tube for attachment to a bulb, and a nozzle attached to said .tube, saidnozzle comprising-a barrel for containing a powder-filled cartridge, and having an open end, a removable tip threadedly engageable .on the open end of said barrel and having a discharge opening, said tip having integrally formed "therewith, a cradle for supporting therein the cartridgefor conveying it into and out of said barrel, said cradleand cartridge being slidably receivable in 'saidbarrel.
